Final answer:
A Peer node status of "Pending" on the MC > Indexer Clustering: Master Node panel signifies that the peer node is in the process of joining the cluster as a worker node but has not yet completed the process.
Step-by-step explanation:
On the MC > Indexer Clustering: Master Node panel, a Peer node status of "Pending" signifies that the peer node is in the process of joining the cluster as a worker node but has not yet completed the process.
During this time, the peer node is waiting for the master node to validate its request and send the necessary configuration information to become part of the cluster.
Once the validation is complete, the status of the peer node will change from "Pending" to either "Connected" or "Failed" depending on the outcome of joining the cluster.
